Have you ever interrobanged?
You may well have done when describing, for example, a lollapalooza or ninnyhammer.
I, to my shame, did so whilst answering an email which contain the word callithumpian.
I fired off a quick emailed query regarding said word to the originator of the email and
I used a multiple interrobang.
I kicked myself ,almost as soon as the email departed my laptop, as realisation
dawned that someone somewhere would know there was a word out there that
I didn't know!
I do now!
